_______________
A. Do a check of the left elevator servocontrols and hinge bearings for too much play and condition (Ref. AMM TASK 27-34-00-200-001).
(1) Do an operational test of the damping measurement (Elevator) (Ref. AMM TASK 27-96-00-710-008):
- if the result of the test is not in the tolerances, see Para. (a)
- if the result of the test is in the tolerances, see Para. (b).
(a) Replace the SERVO CTL-L ELEVATOR, INBD G (34CE1) and the SERVO CTL-L ELEVATOR, OUTBD B (34CE3) of the left elevator (Ref. AMM TASK 27-34-51-000-001) and (Ref. AMM TASK 27-34-51-400-001).
NOTE : The resistance of primary and secondary windings must be
____ between 30 ohms and 500 ohms.
(b) Do the operational test of the elevator and hydraulic actuation (Ref. AMM TASK 27-34-00-710-001).

__________________
A. Test
(1) Do the operational test of the side stick assembly (Activation for the BITE test) (Ref. AMM TASK 27-96-00-710-020).
NOTE : Before you start the operational test procedure, release the
____ FLT CTL/ELAC 1, FLT CTL/ELAC 2 and FLT CTL/SEC 2 pushbutton switches (on these pushbutton switches the OFF legends come on).
(2) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001).
(a) If the ground scanning gives the maintenance message: SEC1 OR WIRING FROM L ELEV POS MON XDCR
- refer to Para. Fault Isolation.
(b) If the ground scanning gives at least two maintenance messages of the list below: SEC1 OR WIRING FROM L ELEV POS MON XDCR SEC1 OR WIRING FROM R ELEV POS MON XDCR SEC1 MON OR WIRING FROM THS ACTR XDCR2 9CE SEC1 OR WIRING FROM L G ELEV MODE XDCR 34CE1 SEC1 OR WIRING FROM R Y ELEV MODE XDCR 34CE2 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 飞行操纵 1(39)
